以迅捷方式禁用 UITextfield 的用户输入

Try this:

Swift 2.0:

textField.userInteractionEnabled = false

Swift 3.0:

textField.isUserInteractionEnabled = false

Or in storyboard uncheck "User Interaction Enabled"

you can use UILabel instead if you don't want the user to be able to modify anything in your UITextField

A programmatic solution would be to use enabled property:

yourTextField.enabled = false

A way to do it in a storyboard:

Uncheck the Enabled checkbox in the properties of your UITextField

Another solution, declare your controller as UITextFieldDelegate, implement this call-back:

@IBOutlet weak var myTextField: UITextField!


override func viewDidLoad() {
super.viewDidLoad()


myTextField.delegate = self
}


func textFieldShouldBeginEditing(textField: UITextField) -> Bool {
if textField == myTextField {
return false; //do not show keyboard nor cursor
}
return true
}

In storyboard you have two choise:

1. set the control's 'enable' to false.

2. set the view's 'user interaction enable' false

The diffierence between these choise is:

the appearance of UITextfild to display in the screen.

1. First is set the control's enable. You can see the backgroud color is changed.
2. Second is set the view's 'User interaction enable'. The backgroud color is NOT changed.

Within code:

1. textfield.enable = false

2. textfield.userInteractionEnabled = NO

   Updated for Swift 3

   1. textField.isEnabled = false
   2. textfield.isUserInteractionEnabled = false

I like to do it like old times. You just use a custom UITextField Class like this one:

//
//  ReadOnlyTextField.swift
//  MediFormulas
//
//  Created by Oscar Rodriguez on 6/21/17.

import UIKit


class ReadOnlyTextField: UITextField {


/*
// Only override draw() if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
override func draw(_ rect: CGRect) {
// Drawing code
}
*/


override init(frame: CGRect) {
super.init(frame: frame)


// Avoid keyboard to show up
self.inputView = UIView()
}


required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)


// Avoid keyboard to show up
self.inputView = UIView()
}


override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
// Avoid cut and paste option show up
if (action == #selector(self.cut(_:))) {
return false
} else if (action == #selector(self.paste(_:))) {
return false
}


return super.canPerformAction(action, withSender: sender)
}


}

Swift 4.2 / Xcode 10.1:

Just uncheck behavior Enabled in your storyboard -> attributes inspector.

If you want to do it while keeping the user interaction on. In my case I am using (or rather misusing) isFocused

self.myField.inputView = UIView()

This way it will focus but keyboard won't show up.

In swift 5, I used following code to disable the textfield

override func viewDidLoad() {
super.viewDidLoad()
self.textfield.isEnabled = false
//e.g
self.design.isEnabled = false
}

textField.isUserInteractionEnabled = false
